Release Notes 1.2.2

1.2.2f1 (2026-07-24)

• Improvements
  • General
    • Default Selection Tool Changed: Changed the behavior so that after running UModelerize, the default selection tool is automatically set to the Object Tool rather than the Box Tool.
    • Restricted arbitrarily adding the Mesh Curves component via Add Component.
  • Modeling Mode
    • Circularize Tool: Improved so that the arc is divided into segments of consistent length.
    • UVParam Tool: Added compatibility to import UV Param values created in UModeler Classic. (??The latest UModeler Classic update is required.)
• Bug Fixes
  • General
    • Fixed an error message that occurred when exiting Prefab Mode with an editable mesh that had modifiers applied selected.
  • Prefab Asset
    • Fixed an issue where the Mesh Renderer was forcibly enabled when exiting Prefab Mode, even though it was set to Collider Mode.
    • Fixed an issue where, when exiting Prefab Mode without saving while Auto Save was off, modeler commands were not cleaned up, making subsequent editing tool selection impossible.
  • Modeling Mode
    • PushPull Tool: Fixed an issue where UV Param values were lost when using the tool.
    • UVParam Tool: Fixed an issue where UV Param values were incorrectly applied when saving a scene/prefab.
    • Position Editor: Fixed the Position value display to be limited to four decimal places.
    • Local Settings Tool: Fixed an issue where scene changes (Dirty state) were not properly detected when changing local settings.
  • PicoBerry
    • Login Hardening: Improved the overall stability of the login system by isolating exceptions related to SignedIn subscribers, adding guard observation logs, and unifying VSA calls.
    • Login Interruption Prevention: Added exception handling so that the entire login process is not interrupted even if loading the VS Attribution type fails during login.

1.2.2 (2026-07-15)

• New Features
  • Modeling Mode
    • Twist Modifier: A modifier that progressively twists a mesh along a specified axis. The higher the position along the axis, the more rotation is applied, making it easy to create twisted shapes as if wringing out a wet towel.
    • Screw Modifier: Rotates an input cross-section (profile) around an axis while simultaneously moving it along the axis. Useful for creating revolved or helical meshes such as bottles, vases, screw threads, springs, and spiral staircases.
• Improvements
  • Data Storage Overhaul (applied since 1.2.1f3)
    • Consolidated the backend into a single source of truth, storing UModeler X's SaveData and mesh assets in a single external Assets/UModelerXData/ folder rather than inside scene/prefab files.
    • As a result, prefab/scene files become lighter, unnecessary diffs and merge conflicts during version control are reduced, and prefab migration stability is greatly improved.
    • (Migration) Existing projects will have their data automatically migrated to the new location on first launch.
  • General
    • Drastically improved the severe wait time that occurred when selecting hundreds of assets at once.
  • UI
    • Added a new slider UI. It replaces most existing size-limited slider UIs.
      • Drag the body left/right to modify the value.
      • Click the body to directly edit the value.
      • Use the mouse wheel while dragging to set the increment/decrement weight.
      • Hover over it to reveal left/right buttons for incrementing/decrementing the value.
    • Hovering over a toolbar icon now displays its hotkey as a tooltip.
    • Added tooltip support to Preferences items.
    • Cleaned up the UI where the property area intruded into its designated range.
  • Modeling Mode
    • EraserTool: Optimized undo memory and deletion speed.
    • Combine Tool:
      • Added a feature to merge only faces on the same Normal Plane. (As before, merging without a normal criterion can be selected via the right-click option.)
      • Added hole-handling logic for cases where a hole remains inside after merging.
    • ArcTool: Added XY axis snap functionality.
  • Rigging Mode
    • Changed the default bone color to white. (3ds Max style)
  • Painting Mode
    • Changed the timing of Paint Data asset creation from when entering Painting Mode to when actual work is performed and Apply is executed.
    • Simplified the information displayed in the Inspector so that unnecessary values are not exposed.
    • Layer: Improved to prevent tool usage when multiple layers are selected.
    • Improved so that tool gizmos are not displayed when a Sticker or Fill Layer is selected.
  • UV Editor / Hotspot Editor
    • Improved an issue where a loading window would intermittently appear and cause stuttering while using the UV Editor.
    • Improved an issue where UV movement was not smooth, as if snapping.
    • Organized the UV/Pixel snap and grid snap of the Hotspot Texturing Editor into a combo box, and improved it so that grid size can be adjusted in powers of two.
• Bug Fixes
  • Modeling Mode
    • Fixed an issue where the Tool Input Hint UI did not work.
    • Fixed an issue where running Isolate after selecting edges caused faces to be selected.
    • Loop Cut Tool / Slice Cut Tool: Fixed an issue where materials became mixed during use.
    • EraserTool: Fixed a bug that occurred when deleting an element consisting only of edges.
    • Fixed an issue where the Mark UV Seam indication did not appear.
  • Painting Mode
    • Fixed an issue where textures appeared differently in Modeling Mode and Painting Mode.
    • Fixed an issue where textures were not saved after applying Hue.
  • UV Editor
    • Fixed an issue where the Enable Alpha Channel option did not work.
    • Fixed an issue where tool property states were not saved in the UV Editor.
  • Save
    • Fixed an issue where the SaveData link was not properly decoupled during prefab creation, along with prefab migration anomalies.
    • Fixed an issue where objects created with UModeler and then made into prefabs were not visible.
    • Fixed an issue where a Reference error occurred during saving.
  • PicoBerry
    • Fixed an issue where the Team Plan asset list was not fully displayed within the Unity Editor.
